Today we discovered about 750 Twitter accounts were broken into and had a link to a webcam site posted on the accounts. It appears other sites and services have been affected by a similar attack. We reset the passwords of the compromised accounts and removed the spammy updates. Our safety team is currently investigating the attack.
As a general reminder, keep in mind that strong passwords can help prevent hijacked accounts. Twitter offers a password strength indicator to help you choose a strong password when you sign up. If you want to change your password now you can do that here. Also, avoid sharing your password with folks or services you don’t feel you can trust.
